We describe the polynomial time complexity algorithm for computing firstcoefficients of the skein (Homflypt) and Kauffman polynomial invariants oflinks, discovered by D.Vertigan in 1992 but never published.

The first coefficient of Homflypt and Kauffman polynomials: Vertigan proof of polynomial complexity using dynamic programming
